雕刻木材——红木国标变化分析 Analysis on the Change of National Standard of Carved Wood-Redwood 原标准（GB/T18107-----2000《红木》） 《红木》新国标树种减少，33种变29种，我们熟知的红木种类“5833”不复存在。对我们之前说过的5属8类33种，《红木》新国标（GB/T18107-----2017《红木》2018年7月1日实施）主要有以下几个改变： The number of new national standard tree species decreased, with 33 varieties and 29 species. The well-known species of mahogany 5833 no longer exists. For the 33 species of 5 genera, 8 classes and 5 genera that we have mentioned before, the new national standard of Redwood (GB/T 18107 - - - implemented on July 1, 2017) has the following main changes: 一、紫檀属花梨木类中的越柬紫檀、鸟足紫檀被认定为大果紫檀的异名，被删除。 1. Among the rosewood species of Rosewood, the Vietnamese and Birdfoot Rosewood were identified as synonyms of Daguo Rosewood and deleted. 越柬紫檀 在红木原材料市场的红木家具市场的固有认知里，越柬紫檀又称柬埔寨花梨，密度0.96-1.01g/cm3，相对较少见。 In the inherent recognition of mahogany furniture market in mahogany raw material market, Rosewood of Vietnam and Cambodia, also known as Huali of Cambodia, has a density of 0.96-1.01g/cm, which is relatively rare. 鸟足紫檀 鸟足紫檀原木市场上一般称老挝花梨，香味较淡，密度0.94-1.01g/cm3。相对大果紫檀来说，树心较扭曲，出材率比较低，纹理变化也比较多。 Birds foot rosewood log market is generally called Lao Huali, with a light fragrance and a density of 0.94-1.01g/cm_. Relative to Daguo Rosewood, the tree core is twisted, the yield is low, and the texture changes are more. 大果紫檀 大果紫檀，传统俗称的缅甸花梨。香味明显比鸟足紫檀、越柬紫檀要浓郁，又称香花梨。密度0.80～0.86g/cm3，树心比较直，出材率较好，纹理较为规则。 在红木市场上，大果紫檀常被称为缅甸花梨，越柬紫檀常被称为柬埔寨花梨或越南花梨，鸟足紫檀常被称为老挝花梨。 从俗称上看似产地上有所区别，但是据木材研究学者宵迪介绍，由于原产地加工对木材加工方式不同，使得后两者外观看起来与大果紫檀有所区别，但实际上这两个树种与大果紫檀同为一个树种，不能区分到产地。目前市场上鸟足紫檀和越柬紫檀的价格与大果紫檀差别并不大，这些树种木材的价格差别主要来自规格和品质，并非原产地。 Daguo Rosewood, commonly known as Burmese pear.
